Dots on leafs
MaxGrowCanadaanswered grow question 4 years ago
Hey,
That appears to be calcium deficiency. Usually caused by low ph in soil. It wont be readily absorbed below 6.2.
I dont see any in your feed schedule, if you're not supplying any, that will it.
Cheers,

Check your PH make sure it is above 6.2. Also add Cal Mag to your nutrient feed. Also try not to over water.

Help, what are those weird yellow spots in late veg?Hello everybody, I've checked in on my plant after I was away from home for 2 day. Now I come back to see these ugly yellow spots? During day 23°C / 55% humid. During night 18°C / 50% humid.
Checked the whole bud, but no insects. My other ideas are mold or stress from the light?Leaves. Color - Yellow

Does anyone know what’s going on here?Hey I have the following problem: A week ago, I bought some cuttings from a seller, but they turned out to be infested with thrips. To tackle this, I used yellow sticky traps and watered with nematodes. I also sprayed BAC Plant Vitality Plus on the leaves.

4 times same genetic but one has hanging leavesThe top right plant´s leaves are hanging down since ~10 days. Don´t think it´s because of over-/underwatering, since I water & feed every plant the same and the others are doing great. Was it maybe too stressfull to set the LED from 160W to 240W on 35cm distance when going 12/12?Week 9

Super thin leafs at the TopThe leaves at the top are super thin, different to the others, the leaves are also darker green, I think it has some kind of problem! It looks like I overwatered it because the leaves are drooping, but that's not the case! Can anyone tell me what the problem could be?Week 6

Leaf Mutation After Topping?So I topped this 10 days (ish) ago. The leaf mutation, I'm wondering if it's actually where I topped it. What do you think? I think cut it pretty damn clean to be honest. I just want to figure out why the leaves are this way. 🍃✌️Week 4

Strange Twisting LeavesI have a plant that's just over 3 weeks old, and since the first week or so, I noticed it has some leaves that grow with a "kink" or "twist." They all seem to have a small discolored spot on the edge of the leaf that eventually becomes the corner of the kink/twistLeaves. Edges burnt

Weird leaf problem. Could be root?Hello community. I am currently growing three plants in the second week of outdoor flowering. I'm using the REMO Supercharger kit.

Not sure what's causing these purple leaves and leaves drying out. Plant overall seems unhealthy near the end of flowering, any suggestions appreciateThis Dos si dos Auto has been struggling over the last couple weeks with upper leaves turning purple and drying out/breaking apart. The buds also look strange to me but that may just be from my inexperience. I'm growing in organic soil and have dry amended twice, 18 days apart.Week 11

Leaves pointing upHello,
One plant has most of its leaves pointing up. Plant look healthy otherwise. PPFD is around 650/700 and light pattern is 20/4
What could be the root cause? I read mixed answers. Some say healthy plants and or strain specific other that light stress.
